NB: this is a working draft; for public launch the plan is to put it on a custom page with a way to sign via lexicon!
The Leaflet crew are driving this, we talked about it in Montreal and got an early look, the goal is to get some shared alignment around what we are all building here and what we think it can grow into.
Go comment there, this is mainly to put this a few places so that people see it who want to help edit (meta / commentary here is fine too, just want to make sure that feedback gets to Brendan).
